What is your question?
Okay I have a 2000 Silverado1500 4x4 5.3LT, did a Tranny swap and everything was good turned over and started all was good. Sat for about 2 more weeks and went out turn over won’t start. Checked all fuses, relays, wiring. Put in a new Crankshaft position Sensor and rewired its plug. I have 8 coil packs and they are getting power but not one is sparking no spark from any of them. I ran a diagnostic reader, Innova 1300, and got 14 P codes: P0101, P0108, P0121, P0125, 0131,0132,0133,0134,0135,0137,0138,0140,0141,0151,0152,0153,0154, P1637,0155,01570158,0160,0161,0171,0172,0174,0175,0200,0230,0300,0325,0327,0332,0335, 0336,0341,0342,0343,0404,0420, These are the C codes: C0225,C0221,0252,0265,0222,0246,0245,0241,0251,0225,0226,0227, C0229, I was thinking since I couldn’t start it or drive it that maybe that’s why so many codes? I never had any codes before and none after Tranny swap. Could someone messing around with my truck cause all these codes? Please help I am at my wits ends. Thanks

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Silverado has multiple issues that could stem from sitting so long and potentially low battery power. If the truck sat idle, it's possible the computer's memory reset or had issues that triggered these codes when the battery drained and recharged. Check your grounding points and ensure the battery is at full charge, as weak voltage can cause the ECM to throw many unrelated codes. Clearing codes after verifying good voltage could be your next step.
